What is the most accurate pedometer on the market?
I always recommend Accusplit to my clients (and I do not have any financial interest in my recommendation). While they may be a little more expensive than other products, they are very good and very accurate. I also like that they have a 5 year warranty without proof of purchase. I have used it once myself because something about the hinge of the pedometer was broken, and the process worked without any problems. Here is a link to their web site: http://www.accusplit.com/Default.aspx
